ROD COUPLING Filed Jan. 28, 1931 INVENTOR 5404051 [Wm/Awe ATTQRNEY Patented July 18, 1933 UNFTEE STATES SALvIUEL F. WILLIAMS, 0 SAN DIEGO, CALIFGB-NIA ROD COUPLING Application filed January 28, 19-31.

My invention relates to rod couplings and the objects of my invention are:

First, to provide a rod coupling in which the means which function to hold the several 5 members of the coupling together are entire ly free from any longitudinally applied compression or tension strains as well as torsional strain, thus providing a rod coupling which readily withstands these strains without separating.

Second, to provide a rod coupling which may be readily connected or separated when desired.

Third, to provide a rod coupling in which the rods may be connected while in proximate alinement or in parallel disposed relation, there being no need of arranging the rods in angular relation to each other in order to effect a coupling.

Fourth, to provide a coupling of this class which is particularly adapted for connecting several sections of rods to form a chain of rods having considerable length, and

Fifth, to provide on the whole a novelly constructed rod coupling which is particularly simple of construction proportional to its functions, durable, efficient in its action and which will not readily deteriorate or get out of order.

lVith these and other objects in view as will appear hereinafter, my invention consists of certain novel features of construction, combination and arrangement ofparts and portions as will be hereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawing and to the characters of reference thereon which form a part of 40 this application, in which:

Figure 1 is afragmentary elevation view of the rod used in conjunction with my rod coupling; Fig. 2 is an assembled elevational view of my rod coupling with the rods shown fragmentarily; Fig. 3 is a sectional view through 38 of Fig. 2, with one of the rods shown in offset relation for illustrating the manner in which the rods are joined; Fig. i is an elevational View of the connecting member; Fig. 5 is an end elevational View Serial No. 511,750.

thereof; and 6 is a transverse sectional view thereof through 66 of Fig. 4:.

Similar characters of reference refer to similar parts and portions throughout the several views of the drawing.

at right angles as shown best in Fig. 1.

A connecting member 2 is provided which includes an enlarged central portion 2a of polygonal cross section. Extending from opposite ends of the central portion 2a are threaded nipple portions 2?) which are externally threaded and are slightly tapered. The connecting member 2 is provided with a bore 20 therethrough having the same diameter as the rod 1. The central portion 2a is provided with a pair of diametrically disposed offset lateral openings 2d which intersect the bore 20. These openings are adapted to receive the offset portions 1?) of the rod members 1 while the bore 20 receives the adjacent portion of their shanks 1a. The connecting member 2 is provided with a pair of slots 16 which are cut into the nipples 2?) so as to intersect the bore 20, and extend into the central portion 2a until opposite their respective lateral openings 255 as shown best in Fig. 3.

The s ots 26 enable the end portion of the rod members 1 to be moved axially into the connecting members 2, while in a slight offset relation thereto as shown in Fig. 3. lVhen O the offset portion 1a of the rod member 1 is opposite the corresponding opening 2d, it is moved radially into the opening and occupies the position shown by dotted lines at the left hand side of Fig. 3, and also shown by solid lines at the right hand side of Fig. 3.

Each lateral opening 2d, corresponding slot 26 and corresponding portion of the bore 20 leave a web 27 which is fully capable of Standing y Of the tensional strain applied to the rod.

Each of the rod members 1 is held in place by a securing nut 3. Each nut 3 is slidably mounted on the rod member as shown best in Fig. 3, said securing nuts being provided with a sleeve portion 30 arranged in centered relation to an internally threaded portion 3?) adapted to screw upon the nipples 2b. The securing nuts are largest around the internally threaded portion 3?) and are preferably polygonal in cross section at this portion. The large end of each securing nut tapers to its other extremity where it is provided with a reinforcing ridge 30 as shown in Figs. 2 and 3.

After the rod members have been positioned with respect to the connecting member 2, the securing nuts are screwed onto the nipple 2?) so that the couplings when joined together appear as shown in Fig. 2.

Though I have shown and described a particular construction, combination and arrangement of parts and portions, I do not wish to be limited to this particular construction, combination and arrangement, but desire to include in the scope of my invention the construction, combination and arrangement substantially as set forth in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. A rod coupling consisting of a rod pro vided with laterally extending portions in opposite directions at its opposite ends, a single piece connector member provided with a channel extending from the center laterally to the outside therein from each end thereof, and a lateral opening from the opposite side of said connector member intersecting each of said channels inwardly from each end of said connector member, each of said chan nels and openings arranged to receive one end of said rod and lateral extending portion, said connector member being threaded at its opposite ends, and nuts adapted to lit over the main portion of said rod and screw on said threaded portions of said connector member for holding said rods in axial a-linement with said connector member.

2. In a rod coupling, a connecting member consisting of a single piece provided with reduced screw threaded portions at its opposite ends, a slot adapted to receive a rod extending from the center outwardly and extending to near the middle portion longitudinally of said connecting member, and a hole extending from the center outwardly from the other side of the middle longitudinally in alinem-ent therewith, and a similar slotand hole in the opposite side of said connecting member in reverse relation thereto.

8. In a rod coupling, a connecting member consisting of a single piece provided with reduced screw threaded portions at its opposite ends, a slot adapted to receive a rod extending from the center outwardly and extending to near the middle portion longitudiir y of said connecting member, a hole extending from he center outwardly from the other side of the middle longitudinally in alinemcnt therewith, a similar slot and hole in the opposite side of said connecting member in reverse relation thereto, a single piece metallic rod with a laterally extending end portion adapted to lit into said slot and its laterally CXtQIU-JHQ, end, extend into the hole on the opposite side of said connecting member from said slot, and a nut shiftably mounted on the body portion of said rod and adapted to screw on the reduced portion of said connecting member and holding said rod in axial alinement with the longitudinal axis of said connecting member.
